This is has (has/is)

The string "This is has" almost always comes from an edit or a fast reword: two finite verbs end up side-by-side. Decide whether you mean a description (is) or possession/experience/present perfect (has), then remove or rewrite the extra verb.

Quick answer

Don't stack verbs. Use "This is..." (or "This is a...") to name or describe. Use "This has..." to show possession, experience, or the present perfect.

Description/identity → "This is..." (This is a problem).
Possession/experience/present perfect → "This has..." (This has improved).
If both ideas are intended, split into two clauses or rephrase.

Core explanation: why "is" and "has" do different jobs

"Is" (the verb be) links the subject to a noun, adjective, or clause that describes it: This is a test. "Has" (the verb have) shows possession or forms the present perfect: This has three parts; This has improved. Putting them together ("This is has...") creates an impossible verb sequence in standard English.

is = linking verb (state, identity, description).
has = main verb for possession or auxiliary in perfect tenses.
If you need both meanings, rewrite: "This is a test, and it has three parts."

Wrong: This is has been a difficult week.
Right: This has been a difficult week.
Wrong: This is has a cracked screen.
Right: This has a cracked screen.

Spacing and hyphenation: how the slip often appears

Often the problem is a typing or drag-and-drop artifact: leftover words, missing spaces, or joined words after an edit. Scan for consecutive verbs immediately after the subject-that pattern is a red flag.

Editing leftover: remove the earlier verb.
Reordering mistake: retype the verb or rephrase the clause.
Joined words: watch for "This ishas" or "This isbeen" after copy/paste.

Wrong: This ishas been fixed.
Right: This has been fixed.
Wrong: This is has delayed delivery.
Right: This has delayed delivery.

Grammar checks and a 3-step rewrite to fix it fast

Quick diagnostics stop the error before you send a message. If those checks leave both options possible, rewrite the sentence.

Q1: Does the next word name or describe the subject? → use "is" (This is a problem).
Q2: Does the clause show possession, experience, or form a perfect tense? → use "has" (This has changed).
If both look correct, split the idea: "This is a problem. It has three causes."

Three-step fix

Step 1: Read the words after the verb to identify noun/adjective versus verb phrase.
Step 2: Say both corrected versions aloud; choose the one that matches your meaning.
Step 3: If ambiguity remains, rewrite into two clauses or a noun phrase.

Wrong: This is has produced mixed results in the pilot.
Right: This has produced mixed results in the pilot.
Wrong: This is has a surprising effect on the sensor.
Right: This has a surprising effect on the sensor.
Rewrite option: The sensor showed a surprising effect.

Real usage and tone: when one choice sounds natural

Formal writing favors precise tense: use "has" for observed changes or outcomes and "is" for definitions or static descriptions. In speech and informal writing you'll hear contractions (This's), but you should still avoid "This is has."

Formal: "This has resulted in a 10% improvement." (result)
Definition: "This is a systematic error in the method." (identity)
Casual: "This has been hilarious tonight!" (experience)

Memory trick and similar mistakes

Two quick questions prevent most errors. The same edit-slip shows up with other auxiliaries, so scan for those too.

Q1 - Does the next word name or describe the subject? → use "is."
Q2 - Does the sentence show possession, experience, or a perfect tense? → use "has."
If both apply, split the idea into two clauses; that's clearer than a double verb.

Watch for related slips: "This is been" → "This has been"; "This is had" → "This has had" or "This had."
Habit to build: read aloud once after major edits and search for common bad strings ("This is has", "This isbeen", "is has").

Wrong: This is been updated.
Right: This has been updated.
Wrong: This is had a problem last week.
Right: This had a problem last week. / This has had a problem recently.

FAQ

Is "This is has" ever correct?

No. Standard English does not allow two finite verbs like that together. Use "This is..." or "This has..." or rewrite into separate clauses.

How do I decide between "This has been" and "This is a" in an essay?

"This has been" reports events or changes with present relevance (present perfect). "This is a" defines or describes identity or quality. If you need both, split into two sentences.

What's the fastest way to find these errors in long documents?

Search for exact strings like "This is has", "This is been", and "is has". Run a grammar checker-most flag unlikely verb pairs.

Can I contract "This has" to "This's has" or similar?

No. Contractions like "This's" represent "This is" or "This has" in speech, but they never create a correct double-verb form. In formal writing, use the full forms.

I'm still unsure - what's the safest fix?

Rewrite to separate the ideas. Example: instead of "This is has three faults," write "This has three faults" or "This is a device with three faults."
